tions before the society. The specialists have continueJ to hold 

 their independent meetings with most satisfactory results. Of 

 late years, by a mutual arrangement, the several Sections have been 

 given precedence at certain specified meetings of the Academy, 

 with the object of bringing before the general meetings the more 

 important communications presented at the less formal Section 

 meetings. 



■ With the object of fostering and encouraging small scientific 

 organizations, especially those composed of younger students, the 

 Academy has freely granted the use of its halls for meetings, and 

 during the past decade the Geographical Society, Delaware Valley 

 Ornithological Club, Philadelphia Botanical Club, Students' Min- 

 eralogical Club, Students' Entomological Society, Myeological 

 Club, Leidy Association, Philadelphia Moss Chapter, Wood's Hole 

 Biological Association, Odontographical and Auti -Tuberculosis 

 Societies and Pennsylvania Audubon Society have availed themselves 

 of this privilege, thus bringing many people in touch with the 

 Academy and eventually adding to its membership. 



Besides these organizations, a number of State and National 

 societies have, during this period, been invited to hold their con- 

 ventions in the building, notably the American Society of Natural- 

 ists, in 1891; the Pennsylvania Veterinarian Society, in 1894; 

 and the American Ornithologists' Union, in 1899. 



The Proceedings and Journal of the Academy have been issued 

 continuously since 1881, as previously. Twenty-one volumes of the 

 former and four of the latter have appeared, comprising in all 

 12,100 pages. These contain contributions not only from the 

 members of the Academy, but from eminent scientists from various 

 parts of America and Europe. 



During the past twenty years the Proceedings have been sent in 

 exchange to a constantly increasing list of scientific societies 

 throughout the world. Beginning with the year 1900 the Acad- 

 emy, through its increased endowment, has been enabled to distrib- 

 ute the volumes to its inembeis, a course that had long been 

 desired. There have also been issued from the Academy and 

 allied societies the Transactions of the American Entomological 

 Society, the Entomological News, and the Manual of Conehology, 

 while the Nautilus has been edited by the Conservator of the Con- 

 chological Section.
